Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-(2,6-Dichlorophenyl)-2,6-dimethylpyridine-3,5-dicarbonitrile (CAS 337924-11-5), a certified reference material (molecular formula C15H9Cl2N3, MW 302.16 g/mol) for analytical method development and quality control.
The molecular framework of 4-(2,6-Dichlorophenyl)-2,6-dimethylpyridine-3,5-dicarbonitrile (C15H9Cl2N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
